[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the existing technology, the traditional filling station uses piston-type filling machine or screw-type filling machine for quantitative filling of ice cream. In practical applications, there are some problems. For example, the filling speed of piston-type filling machine is slow and it is easy to leak liquid, resulting in waste of raw materials and an unclean production environment. Screw-type filling machine has a complex structure and is more cumbersome to disassemble and clean, which is not conducive to maintaining the hygiene of the production environment.

[0018] In view of this, the present invention provides a plunger pump ice cream filling station. Through the cooperation of the frame, hopper, feed pipe, mounting base, servo motor, eccentric crankshaft, pump pipe, plunger, crankshaft connecting rod, discharge pipe, lifting check valve and controller, a plunger-type conveying structure is adopted to increase the sealing between the plunger and the pump pipe and the stability of the plunger's reciprocating motion, so as to realize the stable delivery of ice cream liquid from the feed pipe to the discharge pipe and accurately control the filling volume of ice cream. Compared with the traditional piston filling machine, it has a higher filling speed and a more stable conveying effect, effectively avoiding the leakage problem of ice cream liquid during the conveying process, ensuring the cleanliness of the production environment and the full utilization of raw materials. At the same time, compared with the screw filling machine, its structure is simple, easy to disassemble and clean, and improves the convenience of daily maintenance and cleaning of the equipment.

[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0020] Depend on Figure 1-4 It is known that a plunger pump ice cream filling station includes a frame 1, a hopper 2 is provided on one side of the top of the frame 1, and a feed pipe 3 is connected to the bottom of the hopper 2. A mounting base 4 is provided on the top side of the frame 1 away from the hopper 2. A servo motor 5 is mounted on the side of the mounting base 4. An eccentric crankshaft 6 is rotatably connected inside the mounting base 4. The output end of the servo motor 5 is connected to the eccentric crankshaft 6 for transmission. A pump pipe 7 is provided at the bottom of the mounting base 4, and the input end of the pump pipe 7 is connected to the feed pipe 3. A plunger 8 is movably connected to the inner wall of the pump pipe 7. A crankshaft connecting rod 9 is rotatably connected to the top of the plunger 8. The crankshaft connecting rod 9 is rotatably connected to the eccentric crankshaft 6. A discharge pipe 10 is connected to the bottom of the pump pipe 7. A lifting check valve 11 is installed on the outer wall of both the feed pipe 3 and the discharge pipe 10. A filling pipe 12 is equidistantly connected to the bottom of the discharge pipe 10. A filling head 13 is connected to the bottom of the filling pipe 12. A controller 14 is set on one side of the top of the frame 1. The servo motor 5 is electrically connected to the controller 14.

[0021] In the specific implementation process, it is worth noting that the frame 1 is used to support the ice cream filling device. Through the cooperation between the hopper 2 and the feed pipe 3, the ice cream liquid is stored, and the ice cream liquid is transported to the liquid conveying assembly through the feed pipe 3. Through the cooperation between the frame 1, the mounting base 4, the servo motor 5, and the eccentric crankshaft 6, a reducer is installed at the output end of the servo motor 5. The output end of the reducer is fixedly connected to one end of the eccentric crankshaft 6 via a coupling. The output end of the servo motor 5 drives the reducer to rotate, realizing the rotation of the eccentric crankshaft 6 inside the mounting base 4. Furthermore, the reducer is equipped with an encoder to monitor its rotational speed. The encoder is electrically connected to the controller 14, and the encoder monitors the rotational speed of the eccentric crankshaft. The system measures and transmits the signal to the controller 14. The controller 14 receives and processes the signal to achieve precise control and adjustment of the speed of the servo motor 5, ensuring a stable flow of ice cream liquid during the ice cream filling station of the plunger pump, thus improving filling accuracy. Through the cooperation between the frame 1, feed pipe 3, mounting base 4, servo motor 5, eccentric crankshaft 6, pump pipe 7, plunger 8, crankshaft connecting rod 9, discharge pipe 10, and lifting check valve 11, the servo motor 5 drives the eccentric crankshaft 6 to rotate. Under the drive of the crankshaft connecting rod 9, the plunger 8 is driven to reciprocate within the pump pipe 7. When the plunger 8 moves upward, the lifting check valve 11 connected to the discharge pipe 10 automatically closes. The lift check valve 11 connected to the feed pipe 3 opens under pressure, drawing ice cream liquid into the pump pipe 7. When the plunger 8 moves downward, the lift check valve 11 connected to the feed pipe 3 automatically closes. Simultaneously, the lift check valve 11 connected to the discharge pipe 10 opens under pressure, conveying the ice cream liquid in the pump pipe 7 to the discharge pipe 10, thus achieving a stable delivery of ice cream liquid from the feed pipe 3 to the discharge pipe 10. By controlling the speed of the servo motor 5, the delivery rate of the plunger pump can be adjusted, thereby precisely controlling the amount of ice cream poured. The plunger-type delivery structure increases the sealing between the plunger 8 and the pump pipe 7, as well as the stability of the reciprocating motion of the plunger 8. Compared to traditional piston-type filling machines, this machine offers higher filling speeds and more stable conveying, effectively preventing leakage of ice cream mixture during transport and ensuring a clean production environment and full utilization of raw materials. Furthermore, compared to screw-type filling machines, its simpler structure facilitates disassembly and cleaning, improving the convenience of daily maintenance. Through the coordination of the discharge pipe 10, filling pipe 12, and filling head 13, the ice cream mixture in the discharge pipe 10 is poured into the ice cream container through the filling pipe 12 and filling head 13. Multiple filling heads 13 operate simultaneously, increasing ice cream production efficiency and meeting the needs of large-scale production. The controller 14 controls the entire piston pump ice cream filling station, ensuring the coordinated operation of all components.Through the coordination of the frame 1, hopper 2, feed pipe 3, mounting base 4, servo motor 5, eccentric crankshaft 6, pump pipe 7, plunger 8, crankshaft connecting rod 9, discharge pipe 10, lifting check valve 11, and controller 14, a plunger-type conveying structure is adopted to increase the sealing between plunger 8 and pump pipe 7, as well as the stability of the reciprocating motion of plunger 8. This achieves stable delivery of ice cream liquid from feed pipe 3 to discharge pipe 10 and precisely controls the filling volume of ice cream. Compared with traditional piston-type filling machines, it has a higher filling speed and more stable conveying effect, effectively avoiding leakage of ice cream liquid during the conveying process, ensuring a clean production environment and full utilization of raw materials. At the same time, compared with screw-type filling machines, its structure is simpler, easier to disassemble and clean, and improves the convenience of daily maintenance and cleaning. The specific models of servo motor 5 and controller 14 are not limited, as long as they meet the usage requirements.

[0022] Furthermore, a filter housing 15 is installed on the outer wall of the feed pipe 3. A top cover 16 is fixedly connected to the top of the filter housing 15. A slanted pipe 17 is provided at the bottom of the top cover 16. The slanted pipe 17 is connected to the filter housing 15. A filter cartridge 18 is provided at the bottom of the slanted pipe 17. A side port 19 is provided on the side of the slanted pipe 17 near the pump pipe 7. The interior of the slanted pipe 17 is connected to the feed pipe 3 near the pump pipe 7 through the side port 19. A drain port 20 is provided on the bottom side of the filter housing 15.

[0023] In the specific implementation process, it is worth noting that the drain port 20 is sealed with sealing bolts. When cleaning and maintaining the equipment, the sealing bolts are opened to discharge the impurities filtered out of the filter housing 15 from the drain port 20, which facilitates the cleaning and maintenance of the equipment and ensures the hygiene and stability of the filling equipment. Through the cooperation between the feed pipe 3, filter housing 15, top cover 16, inclined pipe 17, filter cylinder 18, side port 19 and drain port 20, the liquid enters the interior of the filter housing 15 from the feed pipe 3 near the hopper 2, and under the action of conveying pressure, enters the filter cylinder 18 from the outside. The liquid is fed into the inside of the cylinder 18 and the inclined pipe 17, and then conveyed to the feed pipe 3 near the pump pipe 7 through the side port 19. During the conveying process, the liquid is filtered by the filter cylinder 18, so that the impurities and particles in the liquid are filtered out on the outside of the filter cylinder 18. In addition, the liquid filter adopts a detachable design, which makes it easy to clean or replace the filter cylinder 18 regularly. The filtered impurities can be quickly discharged through the drain port 20, which improves the convenience of cleaning and maintenance of ice cream filling equipment, ensures the purity of ice cream liquid and the continuous and stable operation of equipment, thereby improving the product quality of ice cream and the convenience of cleaning and maintenance of equipment.

[0024] Furthermore, a first photoelectric sensor 21 is provided on one side of the infusion head 13, and a solenoid valve 22 is installed on the outer wall of the infusion tube 12. Both the first photoelectric sensor 21 and the solenoid valve 22 are electrically connected to the controller 14.

[0025] In the specific implementation process, it is worth noting that through the cooperation between the discharge pipe 10, the filling pipe 12, the filling head 13, the controller 14, the first photoelectric sensor 21, and the solenoid valve 22, the first photoelectric sensor 21 senses the ice cream box below the filling head 13 and transmits the sensing signal to the controller 14, so that the controller 14 can control the corresponding solenoid valve 22 to open, thereby achieving precise filling of ice cream. When an ice cream box below a filling head 13 is missing, the corresponding solenoid valve 22 is kept closed to avoid waste of liquid due to the missing ice cream box, thereby improving the accuracy and automation level of ice cream filling. The specific models of the first photoelectric sensor 21 and the solenoid valve 22 are not limited, as long as they meet the usage requirements.

[0026] Furthermore, a second photoelectric sensor 23 is installed on both sides of the inner wall of the mounting base 4. The second photoelectric sensor 23 is electrically connected to the controller 14. A limit plate 24 is provided on the top of the outer wall of the plunger 8. The second photoelectric sensor 23 is connected to the limit plate 24.

[0027] In the specific implementation process, it is worth noting that through the cooperation between the mounting base 4, the plunger 8, the second photoelectric sensor 23 and the limiting plate 24, the second photoelectric sensor 23 adopts a through-beam photoelectric sensor. When the plunger 8 rises to a certain position, the limiting plate 24 will block or move away from the beam of the second photoelectric sensor 23, thereby triggering the second photoelectric sensor 23 to send a signal to the controller 14. This allows the control system of the injection equipment to monitor the movement status and movement frequency of the plunger 8, ensuring the accuracy and stability of the injection process. The specific model of the second photoelectric sensor 23 is not limited, as long as it meets the usage requirements.

[0028] Furthermore, a pressure sensor 25 is provided at the end of the discharge pipe 10. The pressure sensor 25 is used to sense the pressure of the ice cream liquid in the discharge pipe 10. The pressure sensor 25 is electrically connected to the controller 14.

[0029] In the specific implementation process, it is worth noting that the pressure sensor 25 is used to sense the pressure of the ice cream liquid in the discharge pipe 10 and transmit the pressure signal to the controller 14 in real time. The controller 14 can accurately control the speed of the servo motor 5 according to the received pressure signal, thereby adjusting the reciprocating speed of the plunger 8 in the pump pipe 7, ensuring that the ice cream liquid is output at a constant pressure, and further improving the accuracy and stability of the filling. The specific model of the pressure sensor 25 is not limited, as long as it meets the usage requirements.
